Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 30, 2024The c.280C>G (p.L94V) alteration is located in exon 3 (coding exon 3) of the CLYBL gene. This alteration results from a C to G substitution at nucleotide position 280, causing the leucine (L) at amino acid position 94 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
